I guess this might be your solution: #31

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. magent2 0.3.2 requires pettingzoo>=1.23.1, but you have pettingzoo 1.22.3 which is incompatible.

not work for me, @joaopedromattos got new error

This is helpful. pip install pettingzoo==1.22

Hey, I'm going to close this issue because I believe the underlying issue here was resolved in #31
